Change File 2

[Yarka]

Hi,
I have a large file as:
a
b
c
d
e
...

I need to have a output as:
a,b,c,d,...

How can I do this?
Thanks.

A starting point:
tr '\012' ',' < /path/to/largefile > output

Hope This Helps, PH.

Hi

Using [tt]awk[/tt] trick kindly showed by vlad :

awk -vORS=, 1 /input.file > /output/file

tr should be much faster than awk, did you try it ?

xargs < my.data|tr ' ' ','

No, I did not tried it, because I am sure a script interpreter can not race against a dedicated tool. This is why I mentioned the [tt]awk[/tt] solution only here in the [tt]awk[/tt] forum, and not in this thread's duplicate too.
